Abstract

(57) [Summary] [Purpose] A dip bag that can efficiently extract coffee.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coffee dip bag which is filled with one cup of coffee powder and which can be easily and sufficiently extracted when the coffee is poured into a container by pouring hot water.

[0002]

[Prior art]

 Conventionally, a coffee dip bag is made of filter paper or the like, as is well known, is filled with one cup of coffee powder, and a hanging thread for hanging the coffee powder is attached to the upper edge portion. When making coffee, hold the above-mentioned hanging thread, put the dip bag in the container, pour hot water, and raise and lower the dip bag to encourage the extraction of coffee.

[0003]

[Problems to be solved by the device]

 However, simply lifting up and down with the above-mentioned hanging thread is not sufficient because the extraction depends on only the contact pressure of hot water against the dip bag to extract the coffee. Cannot be extracted.

Although the above-mentioned operation is necessary for drinking coffee deliciously, there are problems in etiquette, and it is not visually attractive.

The present inventor made various studies on the improvement of the conventional dip bag, devised a dip bag capable of efficiently extracting coffee or red tea, and filed an application for it in advance (Japanese Patent Application No. 3-32101).

This dip bag has a structure in which an expandable tubular body having a closed lower end is inserted into the bag portion and is clamped and fixed to an upper edge of the bag portion. By stirring the bag in a container such as a cup, coffee or tea can be efficiently extracted.

[0007] The above-mentioned invention is effective for black tea, but for powdered coffee, when powdered coffee comes into contact with hot water, gas is generated, so it is difficult for the bag to smoothly enter the hot water, and coffee is not easily extracted. There was a problem that it took time.

The present invention has been made in view of the above circumstances, and if a dip bag filled with coffee powder is put in a container and hot water is poured, coffee can be efficiently extracted without using a spoon or the like. The purpose is to provide a dip bag that can be used.

[0009]

[Means for Solving the Problems]

 In the dip bag according to the present invention, a bag that is filled and sealed with an appropriate amount of coffee powder, a lower tubular body whose outer periphery is held and fixed at the edge of the bag, and slidably inserted into the lower tubular body. A lower portion of the lower tubular body sandwiched and fixed to the edge of the bag of the lower tubular body is formed with an annular inflated portion, and the lower portion of the inflated portion is A constriction is formed in which the side is gently steeper on the upper side, and a diameter-expanded portion is provided at the lower end of the upper tubular body inserted from the upper end of the lower tubular body, and the upper tubular body is inserted into the lower tubular body. When the body is pulled out and the expanded diameter portion is fitted into the expanded portion of the lower tubular body, it has a structure that prevents the upper and lower tubular bodies from moving relative to each other. Has an opening smaller than the diameter of the coffee powder in Serial tubular body is Heat distortion temperature made 1 00 ° C. or more synthetic resin by ASTMD648.

【Example】

 1 and 2 show an embodiment of a coffee dip bag 1 according to the present invention. In the figure, reference numeral 2 is a filter paper, cotton or synthetic resin whose opening edge is sealed by a sealing portion 2a. It is a bag part made as. The bag portion 2 is filled with one cup of coffee powder 3.

At the time of sealing, the lower tubular body 4 is inserted into the bag portion 2 above the seal portion 2a of the bag portion 2, and the outer periphery 4b slightly below the upper end of the lower tubular body 4 is sealed. It is held and fixed to the edge of the bag portion 2 at the same time as the above-mentioned operation.

A portion of the sealed outer periphery 4 b of the lower tubular body 4 is formed slightly thinner than a lower portion 4 c of the lower tubular body 4. An annular expanded portion 7 is formed below the outer peripheral portion 4b. A constriction 8 is formed at the lower end of the inflated portion 7 in which the lower side is gentle and the upper side is steep.

The lower end of the upper tubular body 5 is inserted from the upper end of the lower tubular body 4, and an enlarged diameter portion 9 is provided at the lower end of the upper tubular body 5. When the inserted upper tubular body 5 is stretched, the expanded diameter portion 9 is fitted into the inflated portion 7 of the lower tubular body, and the upper and lower tubular bodies are prevented from moving relative to each other.

The lower tubular body 4 is provided with an opening 4 a for degassing which occurs when hot water is poured into the coffee powder. If the size of the opening is too large, the coffee powder penetrates into the dip bag during storage, which is not preferable, so the size of the opening needs to be smaller than the diameter of the coffee powder. The cross-sectional shape of the opening may be circular, quadrangular, polygonal, or any other shape, and may be slit-shaped. For example, in the case of a slit shape, if the width of the slit is smaller than the diameter of the coffee powder, the coffee powder does not penetrate into the lower tubular body even if the length of the slit is larger than the diameter of the powder.

Although one or more openings can be provided on the side surface of the lower tubular body, the shape shown in (a) or (b) of FIG. 4 is practical in view of industrial mass production.

Since the coffee powder generally has an average particle size of about 50 mesh, the size of the opening may be smaller than 50 mesh in this case.

Further, by inserting the upper tubular body 5 into the lower tubular body 4 having the above-mentioned configuration and fixing the lower tubular body 4 to the opening edge of the bag portion 2, the tubular body 6 composed of the upper and lower tubular bodies 5 and 4 is formed. The dip bag 1 which it has is comprised.

The tubular body 6 is made of a synthetic resin having a Heart distortion temperature (Td) of 100 ° C. or higher according to ASTM D648 so that the strength of the waist is not lowered by hot water.

To make coffee using the dip bag 1, as shown in FIG. 3, the upper tubular body 5 is pulled out, and the expanded portion 9 of the upper tubular body 5 is inserted into the inflated portion 7 of the lower tubular body 4. Lock. Next, the bag portion 2 is put into the container 11, the hot water 12 is poured, and the tubular body 6 is shaken. Since the bag portion 2 is fixed only to the outer periphery 4b near the upper end of the lower tubular body 4, the bag portion 2 shakes with respect to the lower tubular body 4, and the coffee powder 3 is agitated by the lower tubular body 4. At the same time, the hot water inside the bag portion 2 is exchanged with the hot water outside, so that coffee can be extracted efficiently. At this time, the gas generated from the coffee is discharged to the outside through the opening 4a, so that the dip bag is easily immersed in the spout. The dip bag that has been extracted is taken out and discarded.

[0020]

[Effect of device]

 As described above, in the dip bag according to the present invention, the expandable tubular body is fixed to the edge of the bag portion, and the tubular body is provided with the opening smaller than the diameter of the coffee powder for degassing. Therefore, it is compact when not in use and is easy to operate because it is extended when used. Further, the bag portion is easily rocked with respect to the tubular body, and the hot water in the bag is exchanged with the outside while stirring the coffee, so that efficient extraction is performed. In particular, when hot water is poured, the gas generated from the coffee is discharged to the outside through the opening, so that the extraction can be performed more smoothly. Furthermore, since the tubular body attached to the bag is operated, there is an advantage that it does not look like a rude appearance by pressing with a spoon or the like.
